Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0042] Example

[0043] Referring to Figures 1 to 19, this embodiment provides a simple umbrella cover storage device, including a stator 1 and a rotor 2 rotatably connected to the stator 1. The stator 1 is fixedly connected to the umbrella body 3 and forms an accommodating space with the rotor 2. The end of the umbrella cover 4 away from the opening is fixed to the rotor 2. The stator 1 is provided with a plurality of first resistance parts 11 protruding towards the accommodating space side to abut against the inner surface of the umbrella cover 4, or the rotor 2 is provided with a plurality of second resistance parts 21 towards the umbrella body 3 side to abut against the outer surface of the umbrella cover 4. Each resistance part increases the winding resistance by abutting against the umbrella cover 4, so that when the rotor 2 rotates relative to the stator 1, the umbrella cover 4 moves axially along the umbrella body 3 and is wound up in the accommodating space.

[0044] Specifically, when the user needs to use the umbrella cover 4, the umbrella cover 4 is directly pulled down along the opening of the umbrella cover 4, so that the umbrella cover 4 is sleeved downward from the top of the umbrella body 3, which is convenient for the user to operate. When the user needs to store the umbrella cover 4, the rotor 2 is driven by hand to rotate, so that the rotor 2 drives the umbrella cover 4 to axially spiral upward along the umbrella body 3. Since the maximum angle of the rotor 2 is 360° during the rotation operation, there is a pause between each rotation, so the rotor 2 is discontinuous rotation during the winding of the umbrella cover 4. In this embodiment, the first resistance part 11 abuts against the inner surface of the umbrella cover 4 or the second resistance part 21 abuts against the outer surface of the umbrella cover 4, so as to increase the winding resistance, so that the umbrella cover can still maintain the current winding state when the rotor 2 stops rotating, and the umbrella cover 4 is prevented from loosening from the winding state.

[0045] It should be noted that in this embodiment, only the stator 1 and the rotor 2 need to be provided to realize the storage of the umbrella cover 4, which has the advantages of convenient operation, simple structure, few parts and low production cost. When winding, the umbrella cover 4 spirally rises and forms spiral wrinkles in the storage space, the umbrella cover 4 is stored neatly, the volume of the accommodation space can be saved, the overall height of the storage device can be 6-12mm, the appearance of the folding umbrella is not affected, different umbrella bodies can be adapted, and the user can carry it conveniently, especially the female can carry it in a small bag or a handbag.

[0046] In one of the embodiments, the resistance part, the stator 1 is provided with a plurality of first resistance parts 11 on the side facing the accommodation space in the circumferential direction, each first resistance part 11 is arranged in the rotor 2, and forms a first clamping channel with the side wall of the rotor 2. Among them, the top of the first resistance part 11 is used to abut against the inner surface of the umbrella cover 4. For example, five first resistance parts 11 are arranged along the circumferential direction of the stator 1, part of the umbrella cover 4 enters the first clamping channel during winding, and five resistance points are formed by abutting against the inner surface of the umbrella cover 4 under the action of the first resistance part 11. Each resistance point is uniformly distributed in the circumferential direction, so that the umbrella cover 4 is balanced. Preferably, the abutting surface of the first resistance part 11 is an arc surface, which can avoid sharp corners and other sharp edges to pierce or scratch the umbrella cover 4. Fine lines can also be made on the arc surface to increase the roughness of the arc surface, so that the friction between the first resistance part 11 and the inner surface of the umbrella cover 4 is increased, and the winding resistance generated by the first resistance part 11 is increased. The lines on the arc surface can be realized by scribing on the injection mold.

[0047] In another embodiment, the bottom end of the rotor 2 is provided with a plurality of second resistance portions 21 in the circumferential direction towards the umbrella body 3, each second resistance portion 21 forms a second clamping passage with the side wall of the stator 1, and the bottom of the second resistance portion 21 abuts against the outer surface of the umbrella cover 4. When the umbrella cover 4 is rolled up, the umbrella cover 4 passing through the second resistance portion 21 is abutted to form a larger friction, and enters the accommodation space through the second clamping passage, thereby increasing the rolling resistance in the rolling process. In other embodiments, the resistance portion can also be provided as a continuous arc-shaped protrusion or a sawtooth shape, which is not limited thereto and is not specifically limited.

In this embodiment, the volume of the accommodation space can be increased by setting the rotor 2 with different heights, thereby adapting to the umbrella cover 4 with different lengths or widths. In this process, only the rotor 2 needs to be replaced to adapt to the storage volume of different umbrella covers 4, and the stator 1 has high compatibility, which can further reduce the production cost. Further, the rotor 2 is sleeved on the stator 1, and the outer diameter of the rotor 2 is smaller than the outer peripheral dimension of the umbrella body 3.

[0049] Further, one end of the baffle 12 towards the accommodation space is provided with a connecting hole 13, a reverse buckle groove 131 is formed in the connecting hole 13, the rotor 2 is provided with a buckle 23 corresponding to the reverse buckle groove 131, and the buckle 23 is limited by the reverse buckle groove 131 in position; the other end of the baffle 12 is provided with a threaded column 14 for fixed connection with the umbrella body 3. During installation, the stator 1 can be first screwed and fixed with the umbrella body 3, and then the buckle 23 of the rotor 2 is inserted into the connecting hole 13 and limited in position by the reverse buckle groove 131. Or first connect the rotor 2 with the stator 1, and then screw the stator 1 into the umbrella body 3.

The umbrella cover 4 can be fixed by adhesive means, wherein the chuck 24 can ensure that the umbrella cover 4 is spirally rolled up from the outside to the inside in the accommodation space, and at the same time plays a role of clamping the umbrella cover 4, avoiding the fixed end of the umbrella cover 4 from falling off.

[0051] Preferably, the inner top surface of the rotor 2 is provided with a plurality of clamping grooves 25 in the circumferential direction, and the outer periphery of the chuck 24 is provided with a clamping portion 241 corresponding to each clamping groove 25. The chuck 24 is operable to rotate to make the clamping portion 241 engage or disengage with the clamping groove 25. When the clamping portion 241 is aligned with the clamping groove 25, each clamping portion 241 is limited in the axial direction by the clamping groove 25, thereby clamping the umbrella cover 4. When the clamping portion 241 is disengaged from the clamping groove 25, the chuck 24 is not limited and can be directly removed from the rotor 2. In one embodiment, the chuck 24 is provided with a rotating hole 242, and a tool is inserted into the rotating hole 242 to drive the chuck 24 to rotate.

At the same time, the ring piece 41 itself is also a good holding part, which is convenient for the user to pull down the umbrella cover 4. Preferably, the size of the ring piece 41 is close to or slightly smaller than the outer peripheral size of the umbrella body 3, so as to increase the friction between the umbrella cover 4 and the umbrella body 3, so that the umbrella cover 43 can remain in the sleeved state after being sleeved into the umbrella body 33 and is not easy to be folded.
